In addition, the present disclosure may provide various techniques to mitigate collisions between scheduling requests transmitted by a UE, uplink transmissions sent by different UEs, and/or downlink transmis- sions sent by a base station. In an aspect of the disclosure, a method, a com- puter-readable medium, and an apparatus are provided. The apparatus may receive one or more downlink transmissions from a base station. The appa- ratus may determine to transmit an uplink transmission to the base station. The apparatus transmit, to the base station, a scheduling request for the uplink transmission with an ACK / NACK associated with the one or more downlink transmissions using a narrowband NPUSCH format resource structure.
